Invidia Full Titanium Cat-Back Exhaust – 2023-2026 Toyota GR Corolla

Full Titanium Cat-Back Exhaust for the 2023-2026 Toyota GR Corolla

The Invidia Full Titanium Cat-Back Exhaust for the 2023-2026 Toyota GR Corolla is the top-tier exhaust option for the GR4 platform. Full titanium construction throughout, from piping to tips, means significantly reduced system weight versus stainless alternatives, better heat resistance, and the distinctive titanium exhaust note that complements the GR Corolla’s G16E-GTS three-cylinder character. This is Invidia’s best for the GR Corolla.

DETAILS

• Full titanium construction throughout
• Piping diameter: 80mm
• Exhaust tip diameter: 90mm
• Lightweight versus stainless alternatives
• GR4-specific routing
• Direct OEM fitment

The GR Corolla’s G16E-GTS 1.6L three-cylinder turbo produces a distinctive three-cylinder exhaust pulse that titanium piping conveys more clearly than stainless. The 80mm main pipe is sized correctly for the G16E-GTS’s airflow at the power levels this engine produces in stock and lightly modified form. The reduction in system weight removes rear mass from a platform where Toyota worked hard to keep the car light.

Installation is a direct bolt-on replacement using factory flange connections and hanger positions. The GR Corolla’s AWD GR-FOUR system creates a specific underbody layout that Invidia’s application-specific design accommodates correctly, this is not an adapted platform but an engineered GR Corolla exhaust.

Why Choose Invidia

Invidia has been manufacturing performance exhaust systems in Japan since 1999, and in that time they have built a reputation that carries real weight in the tuning community. Every system is manufactured using SUS304 stainless steel and mandrel-bent tubing, which eliminates the flow restrictions and weak points that crush-bent alternatives introduce at every corner. Their in-house engineering team designs each application from scratch rather than adapting a generic template, which is why Invidia fitment is consistently tighter than the competition. The result is an exhaust that installs cleanly, seals correctly, and lasts. Invidia backs their products with a quality standard that is visible in the finish, the weld quality, and the hardware, details that reflect over two decades of refining the same core manufacturing process.

The RallySport Take

The full titanium Invidia is the exhaust we point GR Corolla owners toward when budget is not the limiting factor. It is the correct choice for owners building the GR Corolla toward its potential, the weight savings are real, the material quality is the best Invidia offers, and the three-cylinder engine sounds genuinely different through titanium than through stainless. This fits the 2023-2026 Toyota GR Corolla with the GR4 all-wheel drive system and G16E-GTS engine. No cheaper alternatives match this system at this level of construction.
